Hi, I have purchased some HD content from Itunes. I have my PC connected to my 1080p HDTV but the playback is choppy from my PC. My PC plays other HD files from other sources ok but none from Itunes. I have recently purchased the iphone component cable and was wondering if I could transfer the HD movies to the iphone, to then play on my TV. Is this possible, or is there a more simple way to do it? Thanks in advance for your help.
